Description

Crosstalk Between Channels

RI:

70 dB of isolation between channels. Measured at F

SC

between CH-A,

CH-B, and EXT REF inputs.

Video Out

RI:

Differential Gain (50% APL): Within 1% with a 140 IRE (1.0 V PAL) unit
display.

RI:

Differential Phase (50% APL): Within 1

°

with a 140 IRE (1.0 V PAL) unit

display.

Req: Return Loss (75

W):

30 dB from 50 kHz to 6 MHz.

Description

DC Restorer Clamp Time

RI:

Back Porch.

Frequency Response at 60 Hz (50 Hz PAL)

Req: Attenuation of 60 Hz (50 Hz PAL) on Input signal:

Slow Mode –

20%.

Fast Mode –

90%.

Req: Blanking Level Shift with 10% to 90% APL Change: APL changes from 50% to

either 10% or 90% will cause blanking level shift of 1 IRE unit (7.14 mV PAL) or
less.

Req: Blanking Level Shift Due to Presence or Absence of Burst: 1 IRE unit (7.14 mV

PAL) or less shift from no color burst to presence of color burst.

Description

Sweep

Req: Sweep will occur in all Horizontal mode settings with or without synchronization.

2 FLD Sweep Repetition Rate

RI:

Displays 2 full fields, including the field rate sync between them.

2 FLD Sweep Magnification

RI:

Approximately X20.

1 LINE Sweep Repetition Rate

Req: Equal to the line-rate of applied video or external sync.

2 LINE Sweep Repetition Rate

Req: Equal to half the line-rate of applied video or external sync.

Sweep Length

RI:

2 LINE and 2 FLD sweep length is nominally 12.5 divisions.
